RESUMO

Treatment of oral vascular anomalies (OVA) has focused on minimally invasive techniques rather than radical surgery. We investigated the efficacy and safety of diode laser using the photocoagulation technique in the management of OVA. Forty-seven subjects with OVA were treated with forced dehydration with induced photocoagulation (FDIP) using diode laser (808 nm/4.5 W). This series consisted mostly of male (63.8%) and non-white (63.8%) patients with a mean age of 57.4 years. Varices (91.5%), venous malformations (6.4%), and hemangiomas (2.1%) with a mean size of 7.1 (±4.9) mm were the conditions treated. OVA presented as a nodular lesion (63.8%) involving mainly the lower lip (46.8%). Pulsed laser mode was used as standard and the number of applications varied from one to four sessions, with the majority requiring only one (83%) FDIP session. Kaplan-Meier analysis revealed that complete clinical healing can occur on the 15th day (n=9/29.5%), followed by the 20th (n=6/45.5%), and 30th (n=7/70.5%) days. Postoperative edema was observed in 31 (66%) patients, and recurrence of the lesion occurred in two (4.2%). Based on the data on complete clinical healing, minimal patient discomfort, and satisfactory esthetic results, we can confirm that FDIP by diode laser is a promising candidate for the safe and efficacious treatment of OVA.

RESUMO

Chondroid syringoma (CS) is a benign, slow-growing mixed tumour that arises from the sweat glands and usually presents in the head and neck area. Histopathological examination is important for proper diagnosis, as CS is often confused with epidermal cysts due to its rare presentation. This article presents a man in his 40s with a right upper lip mass that emerged 6 months prior to presentation. An intraoral surgical excision was performed and the histopathological analysis revealed solid epithelial cells that formed multiple, non-branching ducts lined by cuboidal epithelium. Cystic spaces were filled by heterogeneous eosinophilic material embedded in chondromyxoid stroma. Histopathology identified the lesion as an eccrine-variant CS. The patient recovered well.

RESUMO

Using a cross lip vermilion flap for upper red lip reconstruction in cases other than whistle deformity in patients with cleft lip can lead to donor site morbidity. If the practitioner performs primary closure of the mucosa in lower vermilion after flap harvesting, the width and height of lower lip are reduced, which results in an increased lower incisor tooth show. Using free fat grafting is an effective method for reducing donor site morbidity in the lower lip following cross lip vermilion flap harvest.

RESUMO

Lip augmentation can correct lip asymmetries, reduce fine lines, define lip shape and Cupid's bow, and add natural fullness to the lips. Achieving a perfect result when injecting lip filler is an art that combines the desire of the patient with the skill of the practitioner and the practitioner's understanding of the surrounding anatomy. It is essential for aesthetic practitioners to prioritize open communication, provide custom-tailored treatments, and have a strong commitment to achieving natural and harmonious results. By following these principles, patients can enjoy the benefits of enhanced lips that boost their self-confidence while maintaining their unique beauty.

RESUMO

BACKGROUND: Myopericytoma is a rare spindle cell tumor of mesenchymal origin, typically benign, characterized by concentric proliferation of tumor cells around blood vessels within subcutaneous tissue. It primarily occurs in middle-aged adults and is often located in distal extremities, although cases have been reported in proximal extremities and head-neck regions. However, occurrences within the oral cavity are exceedingly rare. To date, literature reviews have identified only two cases in children under 10 years old and reported only five cases of myopericytoma occurring in the lip region. We provide a comprehensive review and analysis of all documented cases to better understand this condition. CASE PRESENTATION: A 7-year-old girl presented to oral and maxillofacial surgery with the discovery of a painless mass on the inner aspect of the upper lip. The diagnosis of myopericytoma was confirmed by histological examination (HE staining), alcian blue staining, and immunohistochemistry. CONCLUSIONS: Following surgical excision, there were no signs of recurrence at a 3-month follow-up. The pathological diagnosis of myopericytoma is quite challenging, and immunohistochemical testing is necessary.

RESUMO

ABSTRACT: Free flaps and their modifications are used to reconstruct multiple large defects in the lip and face. In this study, we present our results on the reconstruction of these defects using bipaddle and sensate free radial forearm-palmaris longus flaps and subsequent revision surgeries. Patient medical records of 11 patients with a mean age of 63.9 ± 12.8 years were retrospectively reviewed. Functional oral competence, lip cosmetics, lip sensation, and donor forearm scars were evaluated using the drooling rating scale, visual analog scale, Semmes Weinstein Monofilament test, and patient and observer scar assessment scale, respectively. The mean dimensions of distal and proximal skin paddles of bipaddle free radial forearm-palmaris longus flaps were 12.7 ± 9.9 and 20.5 ± 3.8 cm2. Mean lengths of the bridge and proximal pedicles were 4.7 ± 1.6 and 5.5 ± 0.7 cm. All the flaps survived. No drooling was observed in the 2 patients without lower lip defects. The mean drooling scores of the 9 patients with lower lip defects were statistically different (Analysis of Variance, pANOVA < 0.00001) at 3, 6, 9, and 12 months postoperatively. The differences between 3 and 12 months were the most significant (pANOVA < 0.00001, pTUKEY < 0.000001). The lip sensation and drooling scores showed a strong positive correlation (r = 0.8504). All patients were able to speak fluently, drink fluid without leakage, and blow a balloon easily. All patients and observers were satisfied with the lip cosmetics, with no significant difference between satisfaction scores (P = 0.087615).There was a statistically significant difference (P < 0.00001) between mean sensation scores of surrounding healthy lip (2.94 ± 0.27) and free flaps (4.15 ± 0.4). All the donor scars healed uneventfully.

RESUMO

BACKGROUND: The increasing number of esthetic procedures emphasizes the need for effective evaluation methods of outcomes. Current practices include the individual practitioners' judgment in conjunction with standardized scales, often relying on the comparison of before and after photographs. This study investigates whether comparative evaluations influence the perception of beauty and aims to enhance the accuracy of esthetic assessments in clinical and research settings. OBJECTIVE: To compare the evaluation of attractiveness and gender characteristics of faces in group-based versus individual ratings. METHODS: A sample of 727 volunteers (average age of 29.5 years) assessed 40 facial photographs (20 male, 20 female) for attractiveness, masculinity, and femininity using a 5-point Likert scale. Each face was digitally edited to display varying ratios in four lip-related proportions: vertical lip position, lip width, upper lip esthetics, and lower lip esthetics. Participants rated these images both in an image series (group-based) and individually. RESULTS: Differences in the perception of the most attractive/masculine/feminine ratios for each lip proportion were found in both the group-based and individual ratings. Group ratings exhibited a significant central tendency bias, with a preference for more average outcomes compared with individual ratings, with an average difference of 0.50 versus 1.00. (p = 0.033) CONCLUSION: A central tendency bias was noted in evaluations of attractiveness, masculinity, and femininity in group-based image presentation, indicating a bias toward more "average" features. Conversely, individual assessments displayed a preference for more pronounced, "non-average" appearances, thereby possibly pointing toward a malleable "intrinsic esthetic blueprint" shaped by comparative context.

RESUMO

Knowledge of the structure of the face is of fundamental importance. In fact, the face is treated in many areas of medicine, from dermatology, to maxillofacial surgery, to otorhinolaryngology, to ophthalmology, etc. and anti-aging aesthetic treatments, and those for the resolution of blemishes are on the increase. For ethical reasons it is not possible to take biopsy samples for facial analysis in the aesthetic field. The main aim of this study was to demonstrate that a high-resolution bimodal ultrasound examination, combined with elastosonography, could be a valid tool for pre-treatment morphological evaluation. To achieve this goal, skin samples were taken from the forehead, zygomatic area, nasolabial fold, upper and lower lip from cadavers to histologically characterize their structure. Subsequently, these same areas were evaluated in vivo using conventional B-mode ultrasound with a 24 MHz high-frequency probe, and elastosonography. The data obtained with the different techniques were compared, in order to state that modern ultrasound techniques can provide similar histological information. The analysis showed that the superficial hypodermis presented a different shape and structure in the different areas, with the exception of the areas of the upper and lower lip, which appeared similar. With aging, the forehead and zygomatic area showed a volumetric increase in the superficial hypodermic layer, while the lip showed non-structural changes. The morphology of the nasolabial fold remained unchanged. When it is not possible to perform histological investigations on the face, to understand its characteristics and dynamics, ultrasound with a 24 MHz probe would seem to be the most suitable method, while elastosonography could be a valid method for evaluating the stiffness of the structural components.

RESUMO

For years, cancer has been one of the diseases that causes the greatest disease burden in the Netherlands. Cancer does not only have a huge impact on patients and their loved ones, but also on society and healthcare. If the number of cancer patients increases further in the coming years, this impact will only aggravate. This development will also impact dental practice. It is therefore important to assess what awaits us in the coming years. Both with regard to supporting and treating (former) oncology patients. Forinstance, detecting secondary effects of cancer treatments such as oral mucositis and medication- and radiation-related jaw necrosis, as well as the early detection of oral cavity carcinomas and sun-related skin damage on the lips and face. Based on this, plans can be made to meet the demand for dental care as well as possible and to reduce the impact of cancer for both the individual patient and for society as a whole.

RESUMO

ABSTRACT: Although the involvement of the nasal passages and nasal septum in cocaine users has been known for decades, a new presentation affecting the nostrils and upper lip with an inflamed appearance has recently been documented. The authors who identified this presentation termed it "cocaine-related plasma cell mucositis" due to the abundance of plasma cells in the infiltrate. In this article, we present a second case and emphasize the dermal involvement of the lip, leading us to consider the condition as a genuine dermatomucositis.

RESUMO

Breast cancer is a heterogeneous set of carcinomas comprising a subgroup of invasive ductal carcinomas and numerous infrequent subtypes. Primary squamous cell carcinoma (SCC) breast is sporadic, accounting for less than 0.1% of all invasive subtypes. Primary metastases to soft tissues of the oral cavity are incredibly rare, amounting to 0.1% of oral malignancies. Diagnosing metastasis to the oral cavity is an enigma to clinicians without pathognomonic signs and symptoms. Here, we report a case of SCC breast, who developed metastatic deposits in the left upper lip after a disease-free survival of 1 year. There are no reports of SCC breast metastasising to the oral cavity, and probably, this is the first such case getting reported. The survival of such patients is abysmal, with most cases surviving less than a year post diagnosis. While treating patients with a history of malignancy, a high degree of clinical presentiment is required.

RESUMO

Congenital lip sinus is a rare entity with upper lip sinus being rarer than the lower lip sinus. It can be an isolated entity or associated with cleft lip, palate or Van der Woude syndrome. Syndromic association requires proper evaluation and aggressive surgical treatment. Preoperative delineation of the sinus tract with ultrasound sonography or MRI is mandatory. Simple excision is sufficient in cases of isolated sinuses. In this article, we report an infant with upper lip sinus managed successfully with simple excision and reviewed the literature.

RESUMO

Ranula is a cyst-like growth that occurs in the oral cavity beneath the tongue. It consists of saliva from a ruptured salivary gland or duct. Rather than just flowing directly from the glands into the oral cavity, saliva permeates the nearby connective tissues and creates a bubble. A ranula could indeed appear at any time span in a person's life for inexplicable reasons. A trauma such as an oral operation, a facial blow or nibbling the lower lip may possibly start one. The following is a case study of an early childhood boy who reported with a swelling in the floor of the mouth with unknown aetiology from the last 6 months.

RESUMO

OBJECTIVES: Reconstruction of large lower lip defects remains challenging in terms of aesthetics, function and safety. The aim of this study is to explore a modified nasolabial flap to repair large lower lip defects. METHODS: The full-thickness nasolabial facial artery flap was used for reconstruction of defects in lip squamous cell carcinoma (LSCC) patients after tumor ablation. The postoperative recovery of patients was obtained through clinical review and follow-up in the first and sixth month. RESULTS: There were four LSCC patients who received tumor ablation at the Beijing Stomatological Hospital of Capital Medical University from November 2022 to March 2023, were included in our study. All patients did not suffer from postoperative infection, orocutaneous fistula, flap necrosis, and flap loss. One patient had the trapdoor deformity. These patients achieved better lip closure function. One patient developed cervical lymph node metastasis 2 months after surgery. CONCLUSIONS: The modified nasolabial flap could achieve good outcomes in terms of aesthetics, function, and safety. It provided a supplementary strategy for the using of nasolabial flap in larger defects of lower lip.

RESUMO

BACKGROUND: Facial infiltrating lipomatosis (FIL) is a rare condition characterized by congenital facial enlargement. Beyond its impact on physical appearance, FIL can also impair essential facial functions such as swallowing, chewing, vision, and breathing, imposing a substantial physiological and psychological burden. Currently, fewer than 80 cases of FIL have been reported, and the characteristics and management strategies for FIL remain unclear. METHODS: We reviewed the clinical, surgical, and radiological records of 39 FIL patients who were treated at our center. Of these, genetic testing was performed for 21 patients. RESULTS: Aberrant overgrowth involves subcutaneous fat, bones, muscles, glands, tongue, lips, and teeth. Epidermal nevi could be observed in the dermatomes innervated by the three branches of the trigeminal nerve, with the highest frequency seen in the dermatome of the mandibular branch. Four patients exhibited concurrent hemimegalencephaly (HMEG), with one case presenting HMEG on the opposite side of the FIL. Nineteen patients were confirmed to harbor the PIK3CA mutation. Thirty-three patients underwent surgical procedures, with a post resection recurrence rate of approximately 25%. CONCLUSIONS: A variety of maxillofacial structures may be involved in FIL. PIK3CA mutations are important pathogenic factors. Emerging targeted therapies could present an additional treatment avenue in the future. However, surgery currently remains the predominant treatment choice for FIL. The timing and modality of surgery should be individually customized, taking into account each patient's unique circumstances. Notably, there is a significant possibility of postoperative recurrence during childhood and adolescence, necessitating early strategic planning of disease management.

RESUMO

Objective: To evaluate the therapeutic effect of a novel air-cooled Nd:YAG laser in the venous lakes of the lips (VLL). Background: The thermal injury is one of the most important issues during laser therapy for venous lakes. Methods: Six pieces of fresh pork livers were used to provide 30 regions with a diameter of 6 mm for experiment in vitro, among which 15 regions were treated by Nd:YAG laser with air cooling until the tissue turned gray-white, whereas the rest were treated without air cooling as control. The operation time of laser irradiation, the degree of temperature increase, and the depth of coagulation tissue were compared between two groups. Then, 60 VLL patients were selected for Nd:YAG laser treatment with or without air cooling. The operation time of laser irradiation, the degree of temperature increase, the postoperative pain visual analog scale (VAS) score, and the percentage of lesions removed within 1 month were compared. Results: In tissue studies, the treated group showed a longer operation time of laser irradiation (p < 0.01), a lower degree of temperature increase (p < 0.01), and there was no significant statistical difference in the depth of coagulation tissue (p = 0.624). In clinical studies, the treated group showed a longer operation time of laser irradiation (p < 0.01), a lower degree of temperature increase (p < 0.01), and a lower VAS score on the 1st and 2nd day, compared with the control group (p < 0.01). Conclusions: Air cooling during Nd:YAG laser for the treatment of VLL can prolong the surgical time, but lowered tissue temperature and reduced patient pain within 2 days under the premise of ensuring the treatment effect.

RESUMO

BACKGROUND: Traditionally, hyaluronidase (HYAL) is used after hyaluronic acid (HA) injection to dissolve the undesired migration of product. OBJECTIVE: To describe a novel lip augmentation technique that uses HA and HYAL simultaneously in patients who previously had HA migration. METHODS AND MATERIALS: Nine hundred twenty female patients were included. In the first group ( n = 793), HA injections were performed in subcutaneous plane of the lips. In the second group who had previous product migration ( n = 127), 7.5 units of HYAL is injected in 4 points in ergotrid area before proceeding with HA injection. RESULTS: The medicis lip fullness scale scores after 2 weeks improved in all patients, while 92% of patients perceived the results as "very much improved" with Global Aesthetic Improvement Scale ( p ˂ .001). There was no difference between 2 groups regarding the patient satisfaction rates ( p ˃.05), while filler migration was seen in 0.2% ( n : 15) of patients in the first group during the follow-up period. CONCLUSION: The new vertical injection approach provided an increased vertical height, optimal eversion, and an incisor display on the lips. The simultaneous use of HYAL before HA injection seems to be a safe and effective practice in 1-stage treatment of the previously injected lips with filler migration into ergotrid area.

RESUMO

PURPOSE: Compromised swallowing, speaking, and local complications are the major disadvantages of established approaches to the posterior tongue and oropharynx. The mandibular split involves an esthetically unpleasant bipartition of the lower lip and is prone to bony non-union or sequestration. The conventional pull-through technique on the other hand lacks the secure reattachment of the lingually released soft tissues. METHODS: The feasibility of a new modified pull-through approach was tested on three anatomical specimens. CAD/CAM cutting guides were used to design a retentive bone flap to properly refixate the genioglossus and geniohyoid muscles after the procedure. The radiographic assessment and treatment planning was performed on 12 cadavers. The entire procedure was tested surgically via dissection in three of those cases. This procedure was then applied in a clinical case. RESULTS: Precise repositioning and dynamic compression of bony segments was possible reproducibly and without injury to adjacent structures. In all dissected cases, a median lingual foramen was found and in two cases vessels entering it could be dissected Radiologic anatomical landmarks were sufficient in all 12 cases to perform the clinical planning procedure. Clinically, the osteotomized segment demonstrated good blood supply and plateless repositioning was verified postoperatively via cone beam scan. CONCLUSION: The method presented is safe and easy to perform. Individual cutting guides improve the safety and accuracy of the procedure, potentially eliminating the need for osteosynthesis. We provide the anatomical and radiologic basis for clinical evaluation of this pedicled bone flap procedure and present the clinical application of this modified pull-through approach.

RESUMO

This study presents a case of atypical manifestation of secondary syphilis. Diagnosis was initiated prompted by the patient's complaint of a lower lip lesion, present for three months, resembling a malignant neoplasm. The lesion, a 3 cm (diameter) ulcerated nodule, arising from conjunctive tissue, raised concern. However, further physical examination revealed additional clinical features, including cervical micropolyadenopathy and erythematous skin lesions, prompting a reevaluation of the diagnosis, most likely secondary syphilis. These findings led to a serological investigation, which, ultimately, confirmed the diagnosis of syphilis. The case underscores the importance of recognizing syphilis as a formidable imitator, posing challenges in establishing differential diagnoses of mucocutaneous diseases.

RESUMO

Perioral tissues are among the first areas to show signs of facial aging, leading many patients to seek perioral fillers as their initial cosmetic treatment. These fillers offer a temporary solution by enhancing volume and reducing common facial lines. Various regions within the perioral area can be targeted, including the lips, nasolabial folds, philtral columns, vertical lip rhytids, oral commissures, melomental folds, mentolabial folds, and nasolabial folds. The technique for injecting perioral fillers depends on the specific region, chosen product, and the desired outcome of augmentation.
